H4 Bulb question

[Joesmoe]

+1 There is a thread somewhere on here where I was (mis)led by my experience -- putting high-wattage bulbs in all my cars, and the Rocket, to me, deserved this treatment.

DON'T DO IT -- at least not with the standard OEM reflectors.

I installed the Eastern Beaver bypass (if I were to do it over, I would go to @DEcosse first) and installed a 130/90 bulb.

Just as @cr0ft warned, the reflector could NOT/NOT handle the high temperature, and while I caught it before it burned through, the marks on the inside bear testament to the misadventure.

I then started following the threads on the LED replacements as suggested above.

In short, it's not the current draw that is the problem (though it could be, and that is another discussion about the rectifier/regulator on our Rockets for which there is a better replacement, which I am in the process of installing with assistance from @DEcosse Bad Voltage Regulator ...OR?)

If the internal reflector is plastic, enough watts will surely melt it. Although the total watts consumed by LED H4's is half what a regular bulb consumes, they do make a good bit of that heat right at the back of the device, where it's little circuit board is. That is what they have a wee little fan on them! The H3's don't have that.

Try these for $60 a piece. Osram LED with 4000/2800 lumen hi/lo. Plug in and cram wiring and off you go. So much brighter and whiter!

I have these 3800 Lumen H4 LED Headlight bulb and absolutely love them. I am still constantly amazed at how bright they are, and how well focused when aimed right. There is a huge thread on them here - 3800 Lumen H4 LED Headlight

I don't know if they have anything newer and better, but these are good. They are a tight fit, and you may have to remove the parking light bulb, but they will fit.

I'm running those In my Dodge Challenger. After I put in the halos the H4's looked really yellow. Been running them over a year without issue.
